Intelligent fire detection

When the fire alarm and detection
system at the Wellcome Trust Centre
for Human Genetics (WTCHG)
needed replacing, Oxfordshire based
Pyrotec Services was asked to look at
the existing system with a view to
total replacement, which included
renewing all existing devices and
control panels, the retention wherever
possible of all existing wiring, the
provision of loop powered sounders,
the enhancement of detection
coverage, and improvement of access
for maintenance purposes in certain
areas, particularly within ceiling voids
and lift shafts. In line with the
University of Oxford Safety Office’s
policy of open protocol systems,
together with commonality of
equipment, Hochiki devices and
Kentec control panels are used for all
replacement and new systems.

It was agreed that the new system
be based around the Enhanced
Systems Protocol (ESP). Stuart
Davies, Hochiki’s marketing manager,
comments: “ESP is a robust total
communications solution for
intelligent fire detection and fully
integrated systems. It has a multipurpose
structure that provides the
flexibility and expansion to
accommodate simple addressable
systems through to integrated
building management and safety
systems. It is a robust system and
perfectly suited for organisations such
as WTCHG, where maximum
reliability and minimum disruption
from unwanted alarms are essential.”
